It reduces particles and sediments larger than 5 microns in diameter effectively, including sediments, rust, dirt, coarse sand, fine sand, and silt, amongst others. Effectively prevents the clogging of water pipes and prolong the service life of your water equipment. You also get a stable and continuous water flow without obvious pressure drop. 5 micron filtration - reduces sediment smaller than the human eye can see, Compared with the 40 micron stainless steel filter, it has a finer filtering effect. Greater Dirt Holding Capacity: These sediment cartridges features multi-layer gradient density and deep grooved design, make it 3 times the dirt-holding capacity of standard 10 inch sediment cartridges, bring a longer life-cycle and saving replacement cost.
